switch mechanisms and at the4 same timehold the inclosing caps to thebase with a yielding pressure.

The object-of my invention is to so construct such a handle of a rotarysn'apswitch that it will be economical and easy to manufacture andassemble, have few parts,

and yet be strong and eliicient in use.

In the accompanying drawings, Figure 1 is a view of the several parts ofmyimproved switch-liano le ready to be assembled, most of the partsbeing shown in section. Fig. 2

is an inverted plan view of the handle w1thout its parts. Fig. 3 is aninverted plan view of the plunger. Fig. 4 is an end view of the spring.Fig. '5 is a plan view of the cup. Fig. 6 is an end view of the handlewith the cup in section before it is secured in place, and Fig. 7 is a asectional view of the corpplete handle. v

molded of suitable insulatin material, and it .is formed with apolygonal ole c, closed at the top of the handle but open at the underside. In this case the hole is shown as of hexagonal section. In thishole is a plunger B, with a head b of corresponding section,

butof sufficiently reduced diameter below to receive a spiral opening S,on which the under side of the plunger-head b may rest,

Fig. 7. lThe handle 1s formed With the usual wings a a and also with acentral hub or projection a2 around the mouth of the open end of thehole a, this projection being sides of the body of the handle, as shownin Figs. 6 and 7. I provide a flan ed sheetmetal retaining-cup C to I itover t 1e outside of this hub or projection, the opposite flanges 4 4'of this cup being of sufIicient depth to project beyond the shoulders3, Fig. 7. This cup is provided with a central hole- 5 of a sizesufficient to permit the .reduced end of the plunger to play through it,butotherwise closing the bottom of the hole a, so that when the partsare assembled the lower end of the sprin will bear on the cup C, whoseIlanges 4 4 ave meantime been bent over the shoulders 3 3 to hold it tovthe body A, Fig. 7. The plunger-has an internally-threaded' hole 8 atits lower end,'Fig. 1, to receive the upper threadedend of theswitch-operating spindle P, Figi?.

In the described constructionV vof switchhandle there are only fourparts, as shown, and the composition body. A can be easily andeconomically molded,'since there is no metallic part to be embedded init, as is common in this class of handles. taining-cup, moreover, beingtted over the projection or hub4 tendsl to strengthen it and The re- 1.The combination ofthe insulating-body Y ofv ,a switch-handle, with aheaded plunger and spring, therein, and a retaining-cup secured to theoutside of the insulatinbody. e body A of the handle is preferably,

2. The insulating-body of a switc -handle, and a headed plunger andspring therein, the said body having a shoulders, in combination with aretainingcup fitting over said projection and flanged over itsshoulders.

In testimony whereof I have signed'my name to thisspecication" 1n thepresende of tWo subscribing witnesses.
